EYE GOGGLES.

Application led February 13, 1922. Serial No. 536,010.

To all whom t may concern:

Be it known that I, HARVEY S. COVER, a@ citizen of the United States, and a resident of the city of South Bend, county of St.

'l Joseph, and State of Indiana, have invented certain new and useful Improvements in Eye Goggles, of which the following is a specification.

My invention relates to improvements in eye goggles especially adapted for use of persons working in dense fumes, gases, poisonous dust, lime, spattering fluids, pathogenic bacteria, viruses, and other injurious substances that injuriously affect the eye and call for complete protection and good vision, the object of the invention being to provide a simple and effective device of vthis character which may be readily applied to the face of the wearer and is highly eificient 1n use.

Other objects will appear hereinafter. Y

.The invention consists in the combinations and arrangements of parts hereinafter de.4 scribed and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which, f

Fig. l is a front face view of a pair of goggles embodying the invention;

Fig. 2 is a section taken substantially lon line 2-2 of Fig. l, and

Fig. 3 is a partial rear view of said goggles.

The preferred form of construction as illustrated in the drawings comprises two chambers 4 connected to ether by a bridge 5, said chambers and bridge being formed of soft and flexible'rubb'er adapted and arranged to seat upon the face of the wearer, to effect a substantially gas-tight seal. An adjustable strap or elastic band 6 is secured to the sides of chambers 4 as shown and is adapted to encompass the head of the wearer, to hold the g ggles in place. The outer wall of each 0 the chambers 4 is provided with a glass late 7 or other sight transparency to permit of vision therethrough, and a retaining wall 8 is extended across the rear lower portion of said chamber as shown, thus leaving an open sight space 9 above. A body of hygroscopic material 10 or common salt is arranged in each of the chambers 4 between the retaining wall 8 and the transparency 7 as indicated, this body of hygroscopie material preferably consisting of common salt or sodium chloride. The transparent wall 7 is preferably in the form of a glass disc seating 1n an annular groove or recess 11 in the walls of the corresponding chamber. The glass disc 7 is made somewhat larger in diameter than the normal diameter of the side walls of the chamber and whereby when placed in position said side walls are stretched and outwardly flared, such stretch.- ing and flaring tending to draw the retaining wall outwardly and forwardly from the face of the wearer, and thus the better retalning the hygroscopic .body of material in place, and conforming to the shape of the lower part of the eye.- Thus the chambers 4 are in open communication with the eyes and adjoining face portions of the wearer and clear, open, unobstructed sight passages leading from the eyes of the wearer to the transparent glass plates 7, are provided.

By this arrangement any moisture present in the atmosphere within the chambers 4 or emanating from the skin or eyes of the wearer will be quickly absorbed and prevented from depositing on the inner face of the sight-glass 7 and thus clouding the vision of the wearer. Thus the eyes of the wearer will be fully protectedy and clear vision assured. Common salt is employed as the hygroscopic element because it is readily obtained at slight cost and because small quantities thereof which might accidentally reach the eyes would be beneficial rather than injurious thereto.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope` of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. Eye goggles comprising chambers having open inner portions adapted yand arranged to seat against and be closed by the face of the wearer and provided i their outer walls with sight transparencies providing open unobstructed sight passages leading from the eyes of the wearer to said transparencies; and means in open communication with but out of said sight passages for preventing deposit of moisture on said transparencies whereby moisture emanating from the person of the wearer passes to said means and is prevented thereby from being deposited on said transparencies, substantially as described.

2. Eye goggles comprising chambers having open inner portions adapt d and arranged to seat against and be cl sed by the face of the wearer and provided in their outer walls'with sight transparencies thus providing clear and unobstructed sight pasages leading from the eyes of the'wearer to said transparencies; and moisture absorbing means in open communication with, but out of said sight passages, for preventing deposit of moisture on said transparencies, whereby moisture emanating from the person of the wearer passes to and is absorbed by said absorbing means, substantially as described.

3. Eye goggles comprising chambers having open inner portions adapted and arranged to seat against and be closed by the face of the wearer and provided in` their outer walls with sight transparencies thus providing open and unobstructed sight passages leading from the eyes of the wearer to said transparencies; and a body of hygroscopic material in open communication with,

but out of said sight passages, for preventing deposit of moisture on said transparencies, whereby moisture emanating from the person of the wearer passes to and is absorbed by said hygroscopic material, substantially as decribed.

4. Eye goggles comprising chambers having open inner portions adapted and arranged to seat against and be closed by the face of the wearer and provided in their iouter walls with sight transparencies thus providing open and unobstructed sight passages leading from the eyes of the wearer to -sald transparencies; and a body of common salt, in open communication with, but out of said sight passages, for preventingdeposit of moisture on said transparencies, whereby moisture emanating from the person of the wearer passes to and is absorbed by said salt, substantially as described.

5. Eye goggles comprisingv chambers adapted and arranged to seat against the face of the wearer and provided in their outer walls with sight transparencles; an inner retaining wall extending across thei lower rear portion of each of said chambers,

there being an open and unobstructed sighty passage above saidl wall; and a body of moisture absorbing means arranged. in each of said chambers between said retaining and outer walls, substantially as described.

6. Eye goggles comprising chambers n'adapted and arranged to seat against the face of the wearer and provided in their outer walls with sight transparencies; an

inner retaining wall extending across the.

`face of the wearer and connected by a bridge, said chambers and bridge being formed of rubber; a band secured to said chambers and adapted to encircle the head of the wearer; a sight glass in the outer wall of each of said chambers, there being an annular groove in the walls of each chamber and said glass being seated in said groove, the diameter of said glass being greater than the normally unstretched diameter of the groove to cause outward stretching of the chamber; an inner retaining wall for each chamber extending across theinner lower portion thereof, there being an open and unobstructed sight passage above said wall, said inner wall being formed of rubber and integral with the wall of said chambers, the

outward stretching of said chamber walls serving to dra-w said inner wall into outwardly flaring form; and a body of hygroscopic substancein each of said chambers and held therein by said retaining wall, substantially as described.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing witnesses.
